Definitions

  • the present invention relates to a control circuit for electrical remote control devices with bistable mechanism such as remote control switches, and comprising motor means, such as a coil, and intended to be traversed by an electric motor current from the network to cause a change. state of the device, the new state remaining maintained without requiring consumption of electrical driving energy.
  • the invention also relates to electrical remote control devices of this type, and in particular remote control switches, timers, relays, time relays, incorporating this circuit.
  • a control device for a bistable or tristable relay intended to be controlled from a DC voltage source.
  • the controlled relay comprises at least two actuating coils with their associated electronic circuit and the desired objective is the switching to one or the other of the coils of the direct current driving pulse.
  • Each coil circuit comprises means sensitive to a drop in resistance of the supply circuit, namely in particular capacitor and resistance.
  • the capacitor of the first coil circuit works in short circuit causing the excitation of a corresponding transistor, then actuation of the coil.
  • the capacitor of the next circuit discharges.
  • the push-button is pressed again, the aforementioned discharged capacitor acts in short-circuit and controls the corresponding transistor to supply the following coil.
  • an electrical remote control device such as a remote control switch, with a bistable mechanism and comprising wound motor means intended to be traversed by an electric motor current from the network to cause a change of state of the device, the new state remaining maintained without consumption of electric driving energy, and means of control actuated for a random period or not to address the electric motor current to the wound motor means, characterized in that the dimensioning of said wound motor means is less than that which would support a continuous passage of the electric motor current or the highest relative voltage to the supply of said motor means, and in that said control means complete an electronic circuit sensitive to a control member which can be actuated, from a current source of the network, for a random duration to deliver, to said means wound motors, a driving impulse of electric current from the network motor, of short duration
  • the present invention proposes to provide such a particularly improved electronic circuit.
  • a particular objective of the invention is to provide such a circuit making it possible to deliver, to said motor means, such as a coil, a short duration pulse that is well calibrated.
  • Another objective of the invention is to produce such a circuit which is particularly reliable.
  • Another objective of the invention is to produce such a circuit making it possible to supply the motor means with the energy necessary for the tilting of a bistable mechanism, which is capable of detecting the release of a manual control member such as a button -pusher, making the device it controls again ready to receive the next command.
  • the invention relates to an electronic circuit for controlling remote control devices, said circuit being intended to be actuated by a control member, for example a push button, associated with an impedance, for example one or more indicator lamps.
  • said electronic control circuit being arranged in the circuit, supplied for example by the network, for supplying a motor means, for example a coil, to the remote control device, by means of said control member, characterized in that it comprises first means sensitive to a drop in impedance of said supply circuit, to remain conductive for a short determined period allowing the motor supply of said motor means, then to cease to be conductive at the end of said duration, and second means sensitive to an increase in impedance of said supply circuit, to become conductive again.
  • the electronic control circuit can comprise a thyristor associated with a resistor in series, with its trigger control means, said thyristor being associated with a diode bridge to be maintained in the conducting state according to each alternating network.
  • the first means may advantageously include a detection circuit sensitive to the drop in impedance in the supply circuit, said detection circuit being associated with the thyristor trigger control means for inhibiting the thyristor at the end of said short determined duration .
  • this detection circuit can comprise a resistor and a capacitor in series, said capacitor being in parallel with a Zener diode controlling a gate control transistor of the thyristor, said capacitor being normally discharged below the conduction threshold of the Zener diode; which then keeps the transistor in the off state, the thyristor trigger then being in the activated state, said capacitor gradually charging in the event of a drop in impedance of the supply circuit until exceeding the conduction threshold of the Zener diode, then causing the inhibition of the thyristor trigger, making the electronic circuit non-conductive.
  • the second means sensitive to an increase in impedance of the supply circuit preferably include a capacitor in parallel with the alternative terminals of the diode bridge to apply, in the event increase in impedance of the supply circuit, a lower voltage on said alternating terminals of the diode bridge, preventing the thyristor control means from inhibiting the trigger current.
  • the remote control device intended to be controlled is a remote control switch represented, schematically, in A and incorporated in a circuit of use aa.
  • This remote control switch A comprises a coil B actuating a bistable mechanism M.
  • the coil B is interposed in the supply circuit bb of the alternating network, for example 220 Volts.
  • control members B1, B2, ... Bn each comprising a push button BP in parallel with a neon lamp serving as indicator indicator N.
  • a push button BP in parallel with a neon lamp serving as indicator indicator N.
  • the coil B of the remote control switch is then subjected to the full power of the supply circuit for the entire period during which the push button is activated, which would require a dimensioning of the coil B capable of resisting this power, clearly superfluous since the bistable mechanism M then tilted for a long time.
  • the electronic circuit according to the invention comprises a diode bridge D interposed on the supply circuit bb, the junctions 1 and 2 of the bridge being connected to the supply circuit bb and the perpendicular junctions 3, 4 to electronic circuit conductors 5, 6.
  • thyristor Th With its blocking diode d and a low resistance in series R. This arrangement allows the thyristor to be traversed by the supply current at each alternation of the network.
  • the gate g of the thyristor Th is actuated by a gate control transistor T interposed between the conductors 5 and 6 with a resistance in series R1 of significant value.
  • the base of transistor T is connected via a resistor R3 to a Zener diode Z leading to the junction between a resistor of significant value R2 and a capacitor C2, this assembly forming said first means, sensitive to a drop in impedance in the supply circuit bb.
  • the second means sensitive to an increase in impedance of the supply circuit, are constituted by a capacitor C1 in parallel with the diode bridge D.
  • the operation is as follows: In the idle state, no push button BP is actuated and the supply circuit bb has a high impedance, of the order of a few kilo-ohms to infinity, depending on the number of organs B1 - Well connected. In this state, the thyristor Th is maintained in the conducting state by means of the trigger resistor R1 at each alternation of the sector coming from the diode bridge, the capacitor C2 being discharged below the conduction threshold of said Zener diode Z, so that the gate current through transistor T is not inhibited.
  • the impedance in the supply circuit bb drops suddenly, allowing the passage of the motor current in the coil B of the remote control switch A so that the bistable mechanism M rocking.
  • a high alternating voltage appears across the diode bridge D, so that the capacitor C2 gradually charges (curve m).
  • the DC voltage of the capacitor C2 exceeds the threshold of the Zener diode Z (instant t1).
  • the transistor T then turns on and inhibits the gate current of the thyristor Th.
  • Zener diode for example, can be replaced by any threshold device, such as for example neon lamp, diac, programmable unijunction transistor etc ...
